Very good item that has already helped me in a number of situations. The portability is a real plus for me. Another plus is that the AAA replacment batteries are readily available at almost every store and gas station.The only additional feature I wish it had is a backlight option. Works quickly and is sensitive enough for wind instruments. The meter is steady and easily read when there is enough ambient light; a backlight switch would help when on a dimly lit stage. Good price, small sizefor portability, and fast readings.
